I will check out the Manufacturer, Excel I believe , for both the Double wall and the Class A pipe.
In The mean time... is there any correlation, between the outside Temp of a double wall pipe and the inner pipe? like 2:1 or something?
Probably not... far too many variables I think.

You been keeping an eye on the stack for smoke? I haven't run the stove myself enough yet, to see how I have to load the various lighter and denser splits, to keep the clean burn going..
